It's natural to worry that someone might try to copy your images online. You do not have to upload your full-quality originals. All files uploaded are specially prepared for safe web display. They are much smaller than your original files, so if anyone tried to enlarge them, they would quickly become blurry and grainy.
It's natural to worry that someone might try to copy your media online. Audio and video uploaded to the site are specially prepared for web playback. The quality is optimized to provide a good viewing and listening experience in a browser while keeping file sizes practical for streaming.
This means the versions available on the site are not intended to replace your original master files. They are generally less suitable for professional editing, remixing, re-encoding, large-screen presentations, commercial production, or other uses where the highest possible quality is important.
Media is delivered using streaming technology rather than as downloadable original files, making it more difficult for others to obtain your source files directly. However, no online system can completely prevent copying, and a determined person could still record media while it is being played. For this reason, you should only upload media that you are comfortable sharing publicly.
